ET2725 Multifunctional Process Calibrator
¤ Super strong protection function: waterproof grade IP67, arbitrary signal end misconnect 220 V automatic protection.
¤ Measurement / output: voltage, current, frequency, resistance, in which current output supports active, passive.
¤ The thermal resistance and thermocouple are simulated in the form of temperature.
¤ Can simulate two-wire transmitter.
¤ The accuracy was 0.02% (ET2725A,ET2726A ) ;0.05% (ET2725B,ET2726B ).
¤ Two isolated channels support synchronous measurement and output.
¤ Can provide manual step, automatic step, 0-100% step and slope output function;
¤ With white LED backlight, manual backlight adjustment and automatic power off function, suitable for field use.
¤ Provide DC24V circuit power suppcalibration;ly for field debugging.
¤ Unique automatic identification of three-wire, four-wire connection mode.
¤ Support customer self,Band on-off test function.
¤ Thermocouple measurement and output provide automatic and manual cold end temperature compensation.
¤ ET2726A,ET2726B can be connected to APSL type high precision intelligent pressure module to realize the pressure measurement function.
¤ Can add new thermocouple, thermal resistance type according to customer needs.
